Application filed December 19,1905. Serial No. 292.441.

Patented sept. s, 1907.

To all whom it may concern:

Be it known that I, ALBERT F. RooKwnLL, a citizen of the United States,residing at Bristol, county of Hartford, State oi Connecticut, haveinvented a certain new and useful Carbureter, of which the following isa full, clear, and exact description, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, forming part of thisspecification.

This invention relates to a carburetor for impregnating air with asuitable fuel, preferably a liquid, whereby the carbureted air will bein a condition `to be subsequently ignited.

The device is particularlyapplicable in connection with explosivemotors, however, I do not limit myself to this particular use, as it maybe combined with other sources of consumption if desired.

One of the objects of the invention is to simplify the construction of acarbureter, whereby the absorption or` intermingling of one of theconstituent elements of the product to be burned with the other'constituent element or elements will be assured.

Another obj ect of the invention is to provide a cheap, durable andsimple construction of carbureter which will be efficient in producingthe desired result.

Other objects and advantages, as well as the novel details ofconstruction of this invention will be specifically set forthhereinafter, it being understood that changes in form, proportion andminor details of construction may be resorted to without departing fromthe spirit or sacrificing any of the advantages thereof.

In the drawings: Figure l is a vertical, longitudinal, sectional viewthrough a carburetor. constructed in accordance with my invention; Fig.2 is a fragmentary cross-sectional View through part of the carburetercasing, showing a part of one of the convolutes of the coil inelevation, together with a part of the supply tube for said coil; Fig. 3is an end elevational view of a slightly modified form of coil g andFig. 4 is a fragmentary cross-sectional view through a part ofthecarbureter casing, showingr part of one of the convolutes of the coilarranged in accordance with the construction shown in Fig. 3, inelevation. I

In the preferred embodiment of my invention as illustrated in thedrawings, I employ a tank l, which is preferably constructed so that itslongitudinal por` tion will be approximately horizontal, the reason forwhich is that a convenient means is provided for incasing a coiled tube2 `within the tank through which the air may pass. The tube 2 has oneend 3 in communication with the outside atmosphere, the remainingportion ofthe tube being illustrated as coiled within the tank or casingl, with its outlet end terminating within the tank l, and adjacent theupper portion of illustrated a ieed tube 4, which passes below thebottoni of the tank, and then enters said tank, being in communicationwith the lower portions of the convolutes of the coil 2 through themedium of the openings 5. i

G designates a Iioat valve ol any preferred construction cooperatingwith the iilling tube 7 of the tank l, which tube may normally be closedby the cap S. I have illustrated a gas dome 9 as leading from the upperportion of the tank l, andadapted to communicate with the source ofconsumption through the medium of a tube l0. In actual practice theliquid will be introduced into the tank l, through the filler tube 7,until the liquid has reached a predetermined level, not wholly lling thetank, however, in order to insure the proper level of the liquid .forthe maximum quan-` tity of the same within the tank, I prefer to utilizethe float valve (i, in communication with the tube 7, so that when asufficient quantity of the liquid has entered the tank, the pipe 7 willclose.

When the liquid has been introduced into the tank part thereof willgravitate into the tube 4, and in its endeavor to seek its level willpass through said tube 4 into the convolutes of the coil 2, through theopenings 5.. Ii the device is to be used in connection with an explosivemotor, the pumping action resulting from the operating of the mechanismusually employed in connection with explosive motors will cause apartial vacuum in that part of the tank designated ll, and above theliquid, so that the air will enter the end 3, of the coil 2, and in itsendeavor` to get into the space ll to destroy the vacuum, said air willforce the liquid through the exit end l2 of the coil 2, so as topractically pump most of the liquid out of the coil 2, permitting it tocommingle with the main body of the liquid. The air which has beenforced through the coil 2 will have become saturated with thehydro-carbon constituents of the liquid, so as to make it combustible bythe time it reaches the place of consumption, for example, an explosivemotor. When it is understood that a liquid is always Iiowing from thetube 4, into the coil 2, through the openings 5, so long as the level ofthe liquid is above the upper portion 4*l of the tube 4, it will beapparent that the air will take up a sutlicient amount of thehydrocarbon constituents of the liquid to carburet it sufficiently tomake it combustible. In other words, after the carbureter has been onceset in operation, there will be a continuous commingling oi the liquidwith the air during the entire time ofthe passage of the air through thecoil, which commingling will only cease when either the air ceases toflow through the coil, or when the level of the liquid is below theportion 4 of the tube 4.

One of the particular advantages resulting from the arrangement hereinshown is that the operation of the device will be eilicient forsupplying, fuel to an eX- plosive motor oi a vehicle which it is topropel, and the eiiiciency oi the carbureter Will in 11o-Wise beaffected on account oi the tilting or vibrations caused by the vehiclepassing over inequalities in the road-bed. In other Words, the tank maybe placed at a considerable angle to a horizontal plane Withoutdestroying its etliciency in any Way, and Where the terms horizontal asapplied to the position oi the tank appears, I Would have it understoodthat I do not limit myself to the position oi' the tank exactly in ahorizontal plane, but I A prefer to maintain the tank in as near ahorizontal plane as will be practical during the passage oi the vehicleover the road-bed.

In the i'orm oi coil shown in Figs. 3 and 4, each convolute 2 isapproximately circular With a constricted or reduced portion at thelowermost point, the walls of the tube at the constricted portion areprovided With openings 5, Alor the introduction ot the hydro-carbon oilinto the tube. In this form the pipe 4 may be dispensed with, and thei'uel permitted to enter the openings 5 by gravitation. Attention isdirected to the tact that the suction in the tubes caused by the vacuumin the chamber Il, and which results in causing a cir- 4culation oi' airto pass through the iree end 3 of the tube, also assists in introducingor drawing the liquid into the coil so that the impregnation of the airwith the iuel interior of the tank, moans for permitting liquid fromsaid l tank to enter independent convolutes of the coil, and an outletport in communication with said tank.

2. The combination with a tank, of a tube having a seseries ot'horizontal coils in said tank, one end of said tube being incommunication with the outside atmosphere and the other end being withinthe tank, means for introducing fluid from the tank through the Walls ofthe coils, each of said coils having a separateA inlet, and an outlettube leading from said tank.

3. A carbureter comprising a tank, a horizontally positioned coiled tubeWithin said tank, the inlet end of said tube being in communication withthe outside atmosphere and the outlet end of said tube being incommunication with the interior of the tank, a tube for conveying partof the liquid in said tank into coils of the tube through sepa rateinlets in said coils, and an air outlet port in communication With saidtank.

4. 'lhe combination with an elongated tank constructed so that itslength is approximately horizontal, a coiled tube within said tank, theseries of coils being approximately horizontal, an inlet end for saidtube being n communication with the outside atmosphere and the outletend of said tube being in communication with the interior of the tank, atube .for conveying part of the liquid in said tank into the coils ofthe tube, and a coperating air outlet port in communication with saidtank.

A carbureter comprising a tank, a coiled tube in said tank having aseries of convolutes, one end of said coil boing in communication withthe outside atmosphere and the other end of said coil being incommunication with the interior ofthe tank, means for permitting liquidto pass into the convolutes of the coil, and means for preventing theliquid level in each convolute from rising beyond a predeterminedheight, 'f1
